To date, data collection of NIH clinical center patients who have received posaconazole is still ongoing and should be completed in early 2010. No data analysis has been performed. Overall, we will identify patients and are looking forward to analyze usage and therapeutic monitoring, especially since we have a number of pediatric patients who have been prescribed posaconazole. We are still hopeful that we will identify risk factors for subtherapeutic levels and use this information to affect our prescribing patterns.
